| 目的 针对纸护角打框机在定长冲切的过程中，速度和位置的双同步跟踪的控制要求，优化纸护角打框机的控制系统。方法 介绍设备及其工作原理，分析并优化控制模型与数学模型，在非同步区引入S曲线进行加减速，并使用外部中断模式进行跟踪控制，最后用Matlab仿真控制曲线。结果 控制模型优化使刀具运动轨迹更加精确，数学模型优化使刀具的位置与速度控制更加精确，外部中断模式实现了跟踪控制。经Matlab仿真，跟踪系数K的曲线是连续的，没有产生阶跃变化。同时满足速度和位置的双同步跟踪的控制要求。结论 经实际使用，纸护角打框机的控制精度高，控制实时性好。使用设计的S曲线加减速控制方法后，纸护角打框机在高速冲切时，减小了噪音和振动，提高了设备寿命和加工精度。 |

| The work aims to optimize the control system of the frame-making machine of paper angle bead, regarding the control requirement of dual synchronous tracking of the speed and position in the fixed-length punching and cutting process of the frame-making machine. The equipment and working principle were introduced. The control model and mathematical model were analyzed and optimized. S curve was introduced in the asynchronous region for acceleration and deceleration, and the external interrupt mode for tracking control was used. Finally, Matlab was used to simulate the control curve. The control model optimization made the cutter track more accurate, the mathematical model optimization made cutter position and speed control more accurate, and the external interrupt mode realizedtracking control. By Matlab simulation, the curve of the tracking coefficient K was continuous without any step change. The control requirements of dual synchronous tracking of speed and position were satisfied. Practical application shows that, frame-making machine of paper angle bead has high control precision and good real-time control. With the designed S-curve acceleration and deceleration control method, the noise and vibration are reduced when the frame-making machine of paper angle bead is punching and cutting at high speed, and the service life and processing accuracy of the equipment are improved. |
